Abstract: The rapid development in the industrial sector leading to the drastic changes in the environmental equilibrium and is the prime challenge to scientists as the natural resources are very precious. The paper industrial effluent mainly shows an adverse effect on the water quality parameters like D.O., B.O.D., C.O.D., pH, temperature and conductivity of the surrounding aqua systems at the time of discharge. The abnormal levels of these parameters cause pollution in water bodies and even death of aqua flora and fauna. However, paper industrial effluents are found hazardous and they enter the environment through various channels of waste water discharges. Conventional treatment technologies for the removal of industrial effluents are economical than that of biological methods. Phytoremediation techniques have been found potential to absorb effluents to maximum extent and without possibility of secondary pollution. The prime objective of this paper is to investigate the capability of selected aquatic plant species of Eichhornia and Pistia for the removal of paper effluent toxicity from the contaminated aqueous environment. The changes in the water quality parameters during the treatment of industrial effluent with aquatic plants were verified periodically to optimize the process.

Keywords: Water pollution, Microbial degradation, Azo compounds, Influencing factors.
Abstract: The discharges of effluent wastewater from the different industries originate adverse effects to the environment and leads to imbalance of bio-systems. Azo compounds are extensively being used as dyes in carpet and textile industries, the water bodies. The conventional treatment technologies for the removal of these dye substances are less economical and cause secondary pollution. Presently, researchers have become increasingly interested to degrade azo compounds by using suitable microbial treatment technologies. The main objective of this paper is to study the capabilities of free, immobilized and co-immobilized cells of Saccharomyces cerevisiae and Lactobacillus sporogenes for the decolourization and degradation of an azo compound ?Congo Red? (CR) from aqueous solutions. The experimental data evidences that the degradation of an azo compound is highly possible with the selected microbial strains and it is more with co-immobilized cells of the selected strains. The influence of various factors viz., pH and initial concentration of biomass on the degradation were verified for the optimization of the process.

Abstract: The dairy industry involves processing raw milk into products such as consumer milk, butter, cheese, yogurt, condensed milk, dried milk (milk powder), and ice cream, using processes such as chilling, pasteurization, and homogenization. Typical by-products include buttermilk, whey, and their derivatives. Since the pollutants generated by the industry are largely lost in production, improvements in production efficiency are recommended to reduce pollutants loads. In this study, a series of experimental studies were conducted with regard to bioconversion of organic fraction of municipal solid waste along with dairy waste water at different C/N ratios using combined composting and vermicomposting technology. The variations in physical and chemical parameters were monitored throughout the process. The results indicate the combined composting and vermicomposting of dairy waste water with municipal solid waste produces high quality compost.

Abstract: Phytase production profile of Bacillus subtilis was investigated here in submerged fermentation with and without enhanced level of fortification by powdered rice bran 9Slurry fermentation). Incorporation of rice bran as substrate particles (5% w/v) in nutrient broth resulted in 5. 11 times better yield of phytase when compared with un-supplemented broth. Among the different substrate particles introduced, rice bran was found to be inducing better phytase productivity. Substrate incorporation at varied concentrations (between 1%-15 % w/v) gave better phytase titers at 9% w/v (41.94 U/mL) of incorporation and 32 hrs of harvest. Acidic medium pH, addition of surfactants after sterilization and bioprocess carried out at 40 ? C were al found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C were all found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C were al found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C and acidic medium pH reiterate the suitability of this phytase as feed premix for poultry.

Abstract: There is an urgent need for the production of valuable chemicals like 1,3- Propanediol from glycerol, a waste product from biodiesel industry. Since 1, 3-Propanediol has biomedical and healthcare applications, it would be suitable to procedure it in an organism with wide acceptability like Lactobacillus reuti. However, lower cell density as well as reduced product titres seem to be the key factors limiting process development. To address these issues, a fed-batch strategy has been presented in the current study. A 4-fold increase in biomass and 25 % increase in biomass and 25 % increase in 1, 3-PD concentration could be achieved in fed-batch as compared to the batch mode of fermentation. Product tolerance assay has revealed that L. reuteri is capable of tolerating 100 g/L of 1,3Propanediol, indicating its potential for industrial application.

Abstract: Release of cotton ginning industry effluents on the agricultural lands causes and indicative change in nutrient cycling and organic matter processing. In the present study, cotton ginning industry effluent discharged soil (test) and undischarge soil (control were collected from the surrounding areas of cotton ginning industry. The physicochemical, biological properties and soil enzyme activities such as amylase. Protease, cellulose and urease were examined. The experimental results indicated that, most of the physicochemical properties such as silt, clay, electrical conductivity, water holding capacity, organic matter and total nitrogen, phosphorus and potassium, microbial population and selected enzyme activities were significantly higher in the test sample than in the control. Additionally, activities were increased with increasing the incubation period up to 21 d over d, however, activities were adversely affected at 28 d. Furthermore, relatively higher activities were observed in soil incubated in the presence of substrate than in the absence of substrate.
